1 Scope

EN 50288-11-1 is a sectional specification for un-screened cables, characterised from 1 MHz up to 500 MHz,

to be used in horizontal and building backbone wiring for Information Technology generic-cabling systems This sectional specification contains the electrical, mechanical, transmission and environmental performance characteristics and requirements of the cables when tested in accordance with the referenced test methods This sectional specification is to be read in conjunction with EN 50288-1, which contains the essential provisions for its application

The cables covered in this sectional specification are intended to operate with voltages and currents normally encountered in communications systems These cables are not intended to be used in conjunction with low impedance sources, for example the electrical power supplies of public utility mains
